No clue, I'm guessing it is a small amount of time. But I never even contemplated HDI till yesterday, have not hunted down injector specs, and don't know how long it takes to squirt out a milligram at unknown pressure at unknown flow rate. That's a measure it and see problem IMHO.

The atmega in the mpguino is most certainly capable of performing accurate fuel consumption monitoring on an HDI with the right programming strategy. It may come back to monitoring the fuel pressure like you said, and applying that and the injector open time to a 2d map formula. It isn't that there are too many variables though, technically speaking.

But it might not be a very practical exercise if a $160 scangauge will tell you what you want to know. You would have to really want the additional precision an injection monitor can provide to go through the effort.
